The sounder ATOVS aboard the NOAA/Metop satellites provides
essential observational information for numerical weather prediction (NWP) to
generate atmospheric analysis fields. Regional ATOVS Retransmission Services
(RARS) are operational arrangements under the World Meteorological Organization
to provide NWP centers with ATOVS data received at RARS direct readout stations
within 30 minutes of observation.
The RARS monitoring pages present the operational information on JMA as a direct readout station, and outline the status of all Asia-Pacific RARS data collected in Tokyo via the GTS regarding navigation, calibration and timeliness.
